I didn't do this for EVERY letter, but the first few AtoZ "expansions" had working booster packs of 15 cards, sorted like so: 11 commons (of 112 possibilities), 3 uncommons (of 117 possibilities) and 1 rare (of 107 possibilities). Which means that every time you refresh this page, you will get a different distribution of cards! Makes a nice palate cleanse before heading into the Encyclopedia's C's. Note that Enhanced By Inferno's Light would have been 5 special packs with set card lists, and B's Broken Links would have come in a 40-page box, so those cards aren't in the booster.

We'll see what that turns out to be, but it won't just be a dilemma.

[125] Missions that say "Any Away Team/crew may attempt" are included in the trigger missions. The design predates 2nd Edition's "Common Ground", and I chose the same picture without realizing.
